The winner of the 2014 James Tiptree Jr. Award for science fiction and fantasy books that explore and expand notions of gender? It's Rupetta by N.A. Sulway, a novel about a 17th century cyborg. And the "honor list" for the award includes a must-read list of books that will challenge your gender preconceptions.

Four hundred years ago, in a small town in rural France, a young woman creates the future in the shape of Rupetta. Part mechanical, part human, Rupetta's consciousness is tied to the women who wind her. In the years that follow she is bought and sold, borrowed, forgotten and revered. By the twentieth century, the Rupettan four-fold law rules everyone's lives, but Rupetta—the immortal being on whose existence and history those laws are based—is the keeper of a secret that will tear apart the world her followers have built in her name.

And here's a complete list of the runners up for the award:
